Abstract

The invention relates to an air spring arrangement consisting of at least: air spring bellows (2) consisting of an elastomer material and comprising two bellows ends, said bellows being mostly provided with an embedded strength support; and a cover and rolling piston (3), each of which has a connecting area (14) for the respective bellows end (8). At least one connecting area is provided with a clamping fit element and a fixing ring (15) which has a clamping functional surface. The inventive air spring arrangement is characterised in that at least one connecting area (14) is shaped like a cone, in such a way as to form the corresponding cone surfaces of the clamping fit element and the fixing ring (15). The clamping occurs automatically when the air spring bellows (2) are subject to pressure, by means of the fixing ring (15), which is also subjected to pressure. The cone-shaped connecting area (14) is also provided with a position support (17) which is used when the air spring bellows (2) are without pressure. Several different embodiments are provided.
